FLUSHING-TANK.

Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed April 28, 1911. Serial No. 623,858.

To all whom it may concern."

Be it known that I, EDWARD KERsnY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flushing-Tanks, of which the following is a specification.

My present invention relates to flushing tanks of that character which are entirely closed and which have means to constantly supply fluid thereto as the pressure within the tank falls below that of the fluid supply, my object being to provide extremely simple and inexpensive means whereby to form a valve for the flushing pipe.

With this in mind my invention resides in the features of construction to be hereinafter described with respect to the accompanying drawing, forming a part of this specification, and in which,

Figure 1 is a central vertical section through my improved tank, and Fig. 2 is a cross-section through the flushing pipe, taken on the line 22 of Fig. 1.

Referring now to these figures, the tank 1, shown in Fig. 1, is entirely closed except for its upper apertured and externally threaded boss 2 and its lower openings, into one of which projects the upper end of the fluid supply pipe 3, this latter constantly supplying fluid to the tank as the pressure within the tank falls below that of the fluid supply. The pipe 3 may be provided with a cut-off valve 1.

Into the other lower opening of the tank 1, which is threaded, is secured the upper externally threaded end of the flushing pipe 5, held in position by means of a lock-nut 6 thereon against the base of the tank 1, and having its upper end formed to provide a seat for a ball 7 constituting the valve. The ball 7 is of hollow construction and is provided with an upwardly extending stem 8, slidably projecting through the lower angu lar end 9 of a guide piece 10 and provided with an upper headed end 11, this guide piece 10 being secured to and depending from a cap 3 The valve 7 and its stem, and the guide piece 10 are lowered into the tank 1 through its upper apertured boss 2, and the cap 3 is screwed tightly over said boss to the position shown in Fig. 1, the ball valve 7 normally remaining in position upon its seat at the upper end of the flushing pipe 5. Adjacent to its upper end, the flushing pipe 5 is provided with an internal spider 12 which forms a bearing for a vertically movable rod 13, this rod 13 having an upper headed end and a lower transverse aperture through which projects the crank 1 1 at the inner end of the angular portion 15 of a valve operating lever 16. As shown, the angular lever portion 15 is extended through a lateral stuffing box 17 forming a part of the flushing pipe 5. Thus, with the parts in the position shown in Fig. 1, the handle portion of the lever 12 is raised in order to oscillate its angular portion 15 and crank 14, which latter causes vertical move ment of the rod 13 to project its headed end upwardly against the ball valve 7 and force the latter upwardly from its seat upon the upper end of the flushing pipe 5. The pressure within the tank 1 immediately forces the fluid therein downwardly through the flushing pipe 5, holding the hollow ball 7 in suspension until the water is practically discharged and suction pulls said ball 7 downwardly and again seats the same. In the meantime as soon as the lever 16 is released, it is lowered to its normal position by means of its weighted end 18.

I claim:

The combination of a tank having an aperturecl boss at its top, a cap removably connected to the boss and provided with a stem extending into the tank, said stem having a guide aperture at its lower end, an outlet for the tank, and a valve controlling the outlet, said valve having a stem which is slidably mounted in the aforesaid aperture.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD KERSEY.
